4 Claims. 1

" This invention relates to a new form of creel and spool-for the supplying of wire to-cut'filling pile-looms-bi the "known continuous wire type and of thenovel-wire -loop type disclosed in mycopending application, Serial -No. 29,802, entitled Methodand-means for the manufacture of'cut In the known continuous wire filling pile'looms,

a wire roll on the far side ofJ-the loom.

' In the wireloop'cut filling pile loom of the type disclosed in my aforesaid U. S. patent application, the wires-which-are woven into the fabric are in the form of continuous loops, the two ends of the wire lengths being butt-welded together.

As mentioned in said patent application, it is sometimes necessary to cut and remove the said wire loops from the loom and insert new wires, the ends of which are then butt-welded together, any resultant slack being taken up by special novel means disclosed in the said patent application. In such cases the new wires must likewise be drawn in from a battery of spools arranged in a creel.

The spools previously used for this purpose develop so many kinks in the wires and result in so much wire slack that the drawing in of said wires is very com'plicative and excessively consuming of both time and wire.

I have now discovered a new form of spool and creel which makes it possible to draw in the wires in a much shorter period of time and with none of the attendant difficulties generally considered heretofore as an inherent characteristic of continuous wire looms. The creel of my invention consists of a multiplicity of horizontal shafts arranged in a vertical series, one above the other. On each of these shafts there are mounted, in a non-rotatable manner, a plurality of spool cases, each of which is provided on its front face with a slot through which the wire can be unwound from the spool enclosed in said case, and, on the rear face, with an opening providing access to said spool to facilitate back-winding in case of slack.

Further characteristics and advantages of my invention will become apparent from the following description read in conjunction with the drawing in which:

iilnzaccordancewith my invention a wire of sufficient length for the type of wire loom contemplated, that is either a wire of very extensive length in the case of continuous wire weaving, or a wire of relatively short length in the case of wire loop weaving, is wound onto hollow, cylindrical core 2 of spool l (Figs. 2, 3 and 5), the end of said wire being first passed through orifice 3 (Figs. 2 and 5) in said core and bent over so as to secure it against slippage. Disc heads 4 and 5 of spool I prevent the wire from sliding laterally off of core 2. Cut-out 6 in core 2 and heads 4 and 5 (Figs. 2 and 3) permits of the fixing of said spools l in a stationary manner on a keyed mandrel, during the spool winding. Spool l fits into case l0 (Fig. 2), consisting of disc H and rim l2, the distance between rim I2 and heads 4 and 5 of spool I being merely suflicient to provide running clearance. At any event this clearance should be less than the diameter of the wire wound on core 2, thus preventing escape of said wire over the ends of heads 4 and 5 and consequent jamming of spool I. As the wire to be wound is generally of a diameter of about 0.006 inch, the clearance on the diameter should be less than this amount. It is to be noted (Figs. 2, 3 and 5) that case it] is open on one side, thus permitting the easy insertion therein of spool I. Rim l2 of said case is provided with slot 14 arranged in a plane parallel to disc ll and extending suitably over about of arc, this slot permitting drag-less withdrawal of the Wire from spool I through an angle capable of being varied within wide limits. The rear portion of case I0 is broken through at It, thus providing access to spool l to facilitate backwinding of said spool in the event of slack forming in the wire.

Case ID is provided with a central opening [3 of non-circular, for instance, square shape, and a plurality of these cases with spools 1 contained therein are mounted by means of this opening l3 onto shafts of non-circular section conforming to the profile of opening l3, for instance square shafts 22 (Figs. 6-9), each shaft being suitably of sufficient length to hold, for instance, 224 such cases. Cases l9 and spools I contained therein, are secured against lateral displacement over said shaft 22 by removable collars 3%, 3| (Figs. 6, 8 and 9) secured to both ends of said shaft. As rims [Z of cases if} extend a somewhat greater amount from discs H than the outside height of spool I (Fig. 5), each spool i is encased by disc I l and rim I2 of one case IE! and disc ll of the adjoining case (see Fig. 9). This arrangement permits of the mounting of a large number of spools l on a given length of shaft 22. Shafts 22 are thereupon mounted in creel 29 (Fig. 6) in such a manner that openings l all face towards the rear of said creel (Fig. 7). As said creel is provided with only one vertical row of shafts 22, any slack experienced in the wires during unwinding may be immediately taken up by merely backwinding the pertinent spools l, without impediment to this backwinding operation being offered by the wires coming from any adjoining vertical row of spools.

Creel 26 (Figs. 6 and 7) consists, for example, of uprights 23 and 24, stayed by cross-members 25 and 23, mounted for instance on carriage 2i. Brackets 28 arranged on uprights 23 and 24 serve for the removable support of shafts 22.

The creel and spool of my invention thus make possible dependable, simple supplying of the wires to be used in continuous wire weaving or wire loop weaving, with provision for the immediate manual taking up of any slack possibly resulting in the wires upon unwinding from their spools.

The foregoing specific description is for purposes of illustration and not of limitation and it is therefore my intention that the invention be limited only by the following claims or their equivalent wherein I have endeavored to claim broadly all inherent novelty.

I claim:

1. A wire creel comprising a planar series of parallel shafts, a plurality of circular spool casings mounted side by side in non-rotatable manner on said shafts, spools rotatably contained in said casings, and a relatively narrow slot circumferentially disposed in each said casing.

2. A wire creel comprising a planar series of parallel shafts, a plurality of circular spool casings mounted side by side in non-rotatable manner on said shafts, and a cut-away portion in each said casing whereby said contained spool may be manually turned.

3. A wire creel comprising a planar series of parallel shafts, a plurality of circular spool casings mounted side by side in non-rotatable manner on said shafts, a relatively narrow slot circumferentially disposed in each said casing, and a cut-away portion in each said casing whereby said contained spool may be manually turned.

4. A wire creel comprising a planar series of parallel shafts, a plurality of circular spool casings mounted side by side in non-rotatable manner on said shafts, each intermediate casing consisting of a tubular section with a single end 010- sure, spools rotatably contained in each said casing and covered by the surrounding casing and the contiguous end closure of the next casing, and a relatively narrow slot circumferentially disposed in each said casing.
